Hello, i need to flash DA14531MOD from an external MCU via one-wire UART.
I have already tried the example BLE_SDK6_examples/interfaces/external-processor-stm32 at main · dialog-semiconductor/BLE_SDK6_examples (github.com)
but i can this load the fw in RAM and not in FLASH.
I can Flash DA14531MOD from SmartSnippets toolbox (one Wire uart) and i need to do the same thing from my MCU.
I need to tell more info in the Header messagge or set some options?
there are some documents or example that describe this option or how to write the Codeless fw in Flash from external MUC uart?
Thank you in advance.
Andrea
Hi Andrea,Thank you for posting your question online.You are right, the Git Examples describe how to load the FW into the SRAM of the DA14531. Unfortunately, we do not have any specific examples/guide on how to load the FW into the SPI Flash via an External MCU.However we provide the ezFlashCLI: GitHub - ezflash/ezFlashCLI: Command line utility to program Dialog Semiconductor Smartbond device family companion flash. Alternate tool to Smarbond devices built in the SDK.You can work with the serailCLI.py file in order to flash your FW into the SPI Flash via an External MCU: ezFlashCLI/ezFlashCLI/serialCLI.py at main · ezflash/ezFlashCLI · GitHubYou should refer also on: AN-B-072: DA1453x Booting from OTP and Serial Interfaces (renesas.com)Best Regards,OV_Renesas
